We've upgraded to Web JetAdmin 10.4 SR1 (10.4.99821) and find that all our newer devices are showing a "Device Communication Error". Models affected are:

HP LaserJet 400 M401dne

HP LaserJet 400 color M451dn

HP OfficeJet Pro X451 dw Printer

HP OfficeJet Pro X476 dw MFD

HP Pagewide 352dw Printer

Older HP devices, Canon devices, etc are all displaying and communicating perfectly. 

 

I've looked through "HP Web Jetadmin 10.4 Installation and Setup Guide" and set the server's IP address specifically everywhere I can. I've made sure that the firewall is not blocking any communication between the server and these devices, yet "Device Communication Error" is the obdurate response. Can anyone suggest what I've missed, or how to tickle the system into successful communication?

Thanks

William

I am having the same problem. The strange thing for me is that my upgrade to 10.4 SR1 seemed to fix the problem until I performed a recent reboot of the server it lives on. This reboot put all of those devices back in error. So I went form a perfectly functioning build to a broken build with nothing but a reboot.

Was anyone ever able to resolve this? I have exactly the same situation. It was working, updated the console, and now the 400series is dead in the water.

Hi All, I'm using HP M602 and M603s with Web JetAdmin 10.4 SR3 and noticed the same device communication errors. I know my network connection and DNS is fine. I noticed that on the machines with device commuication failures the self signed security certificate had expired. On the devices that were fine they were all active well into the future. So I logged into the printer web console and went to the Networking Tab-->Security-->Authorization and then configured a new self signed certificate (we don't have a CA for our printers). 

 

Hope this helps.

Yes it did. My Device Communication Errors immediately went away for all of the printers that I ran this on.

Hi guys.

I tried to assign a new "self-signed-certicate", but this don´t work....

The printers allready had the certificate configured in the future...

 

Still all 400 Series with "Device Communication Error"

 

It would be great if anyone has found a soloution for this.

 

Greetings.

Hi guys,

We are having the same problem with around 150 printers in WJA. We are seeing Device Communication Error on the 200, 300 and 400 series.

 

I have tested the Certification fix as well as updating the firmware on several models without any luck.

WJA version 10.4 (SR 3).

 

Do you have some tips or a fix I can try?

Thank you.
